Vehicles are an important part of transportation, but it is often observed that some vehicles release excessive smoke and pollutants due to poor maintenance or engine-related problems.
In many cases, older or improperly maintained vehicles emit visible black or grey smoke while driving. Faulty engines, incomplete fuel combustion, and lack of regular pollution checks can increase the release of harmful gases and particulate matter into the air.
I have observed vehicles on roads emitting dense smoke, especially during acceleration or while carrying heavy loads. Such emissions contribute to air pollution and reduce air quality in busy traffic areas.
This issue can affect the surrounding environment and may create discomfort for pedestrians, cyclists, and commuters exposed to polluted air regularly.
The problem highlights the gap between pollution-control standards and the actual condition of vehicles operating on roads. Proper maintenance and regular emission monitoring are important to reduce pollution from transport systems.
